Myopia patients can continue to wear keratoplasty lenses after the age of 18, but it is generally not necessary. After the age of 18, myopia can be stabilized if the patient maintains good eye habits. Because the role of keratoplasty is to correct myopia and control myopia progression, patients generally do not need to wear keratoplasty lenses after adulthood, but if the patient’s myopia is unstable, you can prolong the time of wearing keratoplasty lenses. Keratoplasty is a kind of rigid high oxygen permeable corneal contact lens that is worn at night and removed during the day, which is a more effective way to control the growth of myopia. However, there are some risks associated with wearing keratoplasty lenses, such as corneal infection and dry eye. In addition, keratoplasty lenses need to be replaced regularly, which is costly. It is recommended that patients who experience eye discomfort while wearing keratoplasty lenses should consult a doctor promptly to assess their condition and follow the doctor’s instructions for treatment.
